Cardiovascular effects of nasogastric tube feeding in the healthy preterm infant.
Th systemic blood pressure (BP) and heart rate were estimated by the neonatal Dinamap 847 in 16 healthy preterm neonates in active sleep (AS) before, during and after milk feed by indwelling nasogastric tube. The mean arterial blood pressure (MAP) rose by 10.2% (P less than 0.01) and the diastolic pressure by 8.3% (P less than 0.05) during feeding. The systolic and pulse pressures also rose but individual variation rendered these changes insignificant. The heart rate increased by 6.3% (P less than 0.05) 10 min after the end of the feed. The degree of change in BP and heart rate was unrelated to body weight, gestational age, postnatal age, rate of feeding, volume or duration of the feed.
